要实现与您的问题 图 2 中相同的缩放，您必须设置 user-agent 属性 WebView 到 chrome one 如下:

To achieve the same scaling as in Picture 2 from you question , you have to set the user-agent property of WebView to the chrome one as follow :

import QtWebKit.experimental 1.0
...
WebView {    
anchors.fill: parent
url: "http://google.com"   
experimental.userAgent:"Mozilla/5.0 (Windows NT 6.2; Win64; x64) AppleWebKit/537.36  (KHTML, like Gecko) Chrome/32.0.1667.0 Safari/537.36"
}
...

[更新]注意来自 3 个不同用户代理字符串的 3 个图像之间的区别

[Update] notice the difference between the 3 images from 3 different user-agent strings
